'SYRINAGE.

SPECIFICATION forming part of Letters Patent No. 565,516, dated August 11, 1896. Application filed ootober 13, 1894. Serial No. 525,850- (Nomodel.)

To all whom it may concern.-

Be it known that I, WILLIAM P. SHATTUCK, of the city ofMinneapolis,.county of I-Iennepin, State of Minnesota, have invented acertain new and Improved Vaginal Syringe, of which the following is aspecification.

My invention relates to vaginal syringes, and the object I have in viewis to provide a neat and convenient syringe for female use which is notonly adapted to act as a receptacle for the water before it is forcedinto the vagina, but also to receive the water and mucus as it flowsback out of the vagina when the operation of syringing has beensuspended.

My invention consists, further, in a valve provided in the end of thesyringe that is to be inserted into the vagina, which prevents theescape of any liquid out of the syringe when not in use, and which canbe quickly opened to permit the free passage of water or other liquid orclosed to prevent the flow thereof Without removing the syringe from thevagina.

My invention consists generally in a suitable receptacle for water orany other liquid provided with a reduced extension and connectedwith abulb for forcing the liquid out of the receptacle through perforationsand a central opening in the end of the extension, a valve adapted toclose both the perforations and the central opening, and a loose ballarranged below the valve and adapted to close the central opening whilethe liquid is being forced through the perforations and to roll away andallow the liquid to flow back into the receptacle through thecentralopening when the operation of syringing has been suspended, allas hereinafter described, and particularly pointed out in the claims.

'In the drawings forming part of this specification, Figure 1 is a sideelevation of a syringe embodying my invention, the receptacle beingshown in vertical section. Fig. 2 is a vertical section of a portion ofthe reduced extension of the receptacle, showing the valve, the centralopening, and a ball covering the same. Fig. 3 is a plan view of thevalve-disk. Fig. 4 is an end View of the reduced extension, showing thecentral openin g and the perforations surrounding it.

In the drawings,- 2 represents the receptacle or main portion of thesyringe, constructed of any suitable material, preferably metal, andprovided with a reduced extension 3 of suitable size and shape. Thereceptacle is also provided with an opening 4 in its wall, and athreaded cap 4 is provided that is adapted to screw into the wall of thereceptacle, covering the opening 4 therein. The cap 4 may be removed atany time when it is desired to fill or empty the receptacle, and agasket 5 is provided under the cap 4:, which prevents the escape of anyof the liquid from the receptacle. Extending through the wall of thereceptacle and formed integrally therewith is a pipe or tube 6, whichextends into the interior of the receptacle for a considerable distance,for the purpose hereinafter described.

The reduced extension 3 is provided in its end with a central opening 7,and a series of perforations 8 are arranged around said opening, and aball 8 is provided that is adapted to cover the opening 7. Above theperforations and the central opening and formed integrally with theinterior of the reduced extension is a suitable valve-seat 9 for a disk10, which forms a tight joint with the seat by means of suitable ringsor packing between them. The disk 10 is provided with a stem 11, whichextends up through the interior of the receptacle and through the endwall thereof and with the guide-lugs 10. The end wall is provided withan inwardly-projecting stud 12, having a cam-surface on its inner end,and a pin 13 is arranged to project through the stem 11 and to travelupon the cam-surface of the stud 12 when the valve-stem is turned ineither direction. A slight movement of the stem serves to open or closethe valve.

A stuffing-box 15 is provided through which the stem 11 passes, and aspiral spring 16 is coiled around the stem 11 between the cap and thehandle 17 on the end of the stem.

The spring 16 tends to keep the valve open receptacle and bulb and thepipe leading thereto are then filled with water or other liquid throughthe opening 4. The cap 4 is then screwed down and the reduced extension3 inserted into the vagina. The valve is then opened and the water orother liquid forced out of the receptacle into the vagina by squeezingthe bulb 19. As the liquid is forced into the end of the reducedextension 3 the ball will be driven over the central opening 7 and heldin that position as long as pressure is applied to the bulb. The centralopening being closed, the water or other liquid will pass out throughthe perforations 8 and will eifectually spray the walls of the vagina.After the pressure is removed from the bulb the ball will roll away fromthe central opening and the liquid and mucus collected by it in thevagina will flow back into the receptacle through the central opening 7.The mucus will settle to the bottom of the receptacle, leaving theliquid around the tube 6 comparatively clear. If it is desired to usethe syringe again before emptying it, the tube 6, extending into thereceptacle, will enable the person operating the syringe to force theclear liquid in the top of the receptacle into the vagina withoutdisturbing the matter which has settled to the bottom. After the liquidhas all passed back into the receptacle the valve is closed and thesyringe removed.

The syringe, in traveling, can be carried full of water or other liquidin a hand-bag or other receptacle, and can be used in places where anordinary syringe could not be used. After the syringe has been used, asall of the liquid goes back into the receptacle, the syringe can beagain closed and put away without emptying the liquid therefrom.

The syringe is also especially adapted for the use of invalids orpersons who are so sick that any movement of the body is difficult.

Having thus described my invention, I claim as new and desire to coverby Letters Patent 1. A syringe, comprising the main portion orreceptacle, provided with a reduced extensionhavin g an opening in itsend, and a series of perforations surrounding the same, means forclosing said opening whereby the liquid in said receptacle may be forcedout through said perforations, a valve at the outer end of saidextension and arranged to be Within the vagina when the syringe is inuse, and means for opening or closing the same after insertion to permitthe use of said syringe or to prevent the accumulated liquid fromrunning out of said extension while said syringe is being removed,substantially as described.

2. Asyringe, comprisingareceptacle 2 having an extension 3 provided atits outer end with a central opening, and having a series ofperforations surrounding the same, a ball adapted to close said centralopening, while the liquid is being forced through said perforations, andto roll away to permit the liquid to flow back into said receptaclethrough said opening, a valve 10 arranged at the extreme outer end ofsaid extension, and means for opening or closing said valve afterinsertion to permit the use of said syringe or to prevent theaccumulated liquid from running out of said extension while said syringeis being removed, substantially as described.

3. In a vaginal syringe, the combination with a suitable end or nozzleprovided with a central opening, and a series of perforations arrangedaround said opening, and means for forcing liquid through saidperforations, of a valve for closing said opening, and a ball arrangedto close said central opening while the liquid is being ejected throughsaid perforations, and to move away and allow the liquid to flow backthrough said central opening, substantially as described and for the punpose set forth.

i. A syringe, comprising the main portion or receptacle, provided with areduced extension 3 having an opening in its end, a valve arranged atthe outer end of the extension to close said opening, and means foropening the Valve after insertion to permit the use of said syringe, andfor closing the valve after
